Namespace:  System.Net
Assembly:  System (in System.dll)

'Declaration

	authenticationModule As IAuthenticationModule _
)

Parameters

authenticationModule
Type: System.Net.IAuthenticationModule

The IAuthenticationModule to register with the authentication manager.

ExceptionCondition

authenticationModule is Nothing.

The Register method adds authentication modules to the end of the list of modules called by the Authenticate method.

If a module with the same AuthenticationType is already registered, this method removes the registered module and adds authenticationModule to the end of the list.

The following example registers an authentication module with the authentication manager. For a complete example, refer to the AuthenticationManager class.

   ' This is the program entry point. It allows the user to enter  
   ' her credentials and the Internet resource (Web page) to access. 
   ' It also unregisters the standard and registers the customized basic  
   ' authentication. 
  Private Overloads Shared Sub Main(ByVal args() As String)

    If args.Length < 4 Then
      showusage()
    Else 

      ' Read the user's credentials.
      uri = args(1)
      username = args(2)
      password = args(3)

      If args.Length = 4 Then
        domain = String.Empty
        ' If the domain exists, store it. Usually the domain name 
        ' is by default the name of the server hosting the Internet 
        ' resource. 
      Else
        domain = args(5)
      End If 
      ' Unregister the standard Basic authentication module.
      AuthenticationManager.Unregister("Basic")

      ' Instantiate the custom Basic authentication module. 
      Dim customBasicModule As New CustomBasic()

      ' Register the custom Basic authentication module.
      AuthenticationManager.Register(customBasicModule)

      ' Display registered Authorization modules.
      displayRegisteredModules()

      ' Read the specified page and display it on the console.
      getPage(uri)
    End If
